Abstract: A method is disclosed for the non-destructive determination of the pore size distribution and the distribution of fluid flow velocities using NMR spin echo signal measurements. In one embodiment, the invention involves simultaneously injecting acoustic energy (208), generating a magnetic field having a gradient, and injecting radio-frequency electromagnetic energy (206) into a subsurface region, using for example an NMR tool and a well logging tool having an acoustic transmitter placed in a wellbore (202). The spin echo signal generated in the subsurface region is measured (210) by the NMR tool for at least two values (212) of the magnetic field gradient. A relationship is provided by which the pore fluid velocity distribution may be calculated (214) from the inverse Fourier transform of the spin echo data. The pore size distribution may then be calculated from the pore fluid velocity distribution.

Abstract: A reverse-flow nozzle generates a cavitating and/or pulsed jet of pressurized liquid. The nozzle includes a body having an inlet for receiving a stream of liquid and a main channel through the body extending from the inlet to an outlet. A flow-reversing channel in the nozzle diverts a portion of the liquid from the main channel to a point downstream of a mixing chamber. The channel returns the diverted liquid back into the mixing chamber as a reverse- flow jet relative to a main stream of liquid flowing toward the outlet. This reverse-flow jet interacts with the main stream to generate the cavitating jet that discharges from the outlet. By angling the reverse-flow jet relative to the main stream, a naturally pulsed jet may be generated.

Abstract: A hearing aid has means (15) for detecting fast transients in the input signal and means (16, 12, 13) for attenuating the detected transients prior to presenting the signal with the attenuated transients to a user. Detection is performed by measuring the peak difference of the signal upstream of a band split filter bank (11) and comparing the peak difference against at least one peak difference limit.  Then, if a transient is detected, a state machine (20) analyzes the peak level and the absolute average level of the signal and engages a gain calculator (12) to follow either the peak level or the absolute average level of the input signal for at least the duration of the transient in order to attenuate the transient. The engagement of the gain calculator (12) is performed in each frequency band dependent of the detected transient. The invention further provides a method for detecting fast transients.
